%X Purpose: The performance and possibilities of application of modified Jominy-test (JMC -test) in computer simulation of high-hardenability steel quenching were investigated. JMC -specimen and cylindrical specimen has similar cooling curves if the cylindrical specimen has been quenched in oil or cooled in air.Design/methodology/approach: The performances of investigated JMC -test have been estimated by comparison of cooling curves of JMC -specimen and cylindrical one cooled in different quenchants.Findings: Based on the sufficiency of both, time of cooling and similarity of cooling curves of investigated workpieces and JMC -specimen it can be concluded that JMC -test can be accepted as very useful test for estimation of the hardness of quenched workpieces made of high-hardenability steels.Research limitations/implications: The cooling curves of JMC -specimen and the cooling curves of cylindrical specimens have been given by computer simulation and more experimental researches are advisable.Practical implications: The simulation of quenching based on modified Jominy-test can be applied for steels with high hardenability. This method of simulation is especially suitable for tools and dies steels.Originality/value: Using the results of simple modified Jominy-test (JMC -test) in numerical modeling of steel quenching it is possible to simulate hardness in quenched specimen of high-hardenability steel.
